The composition ofmathides principally by means of a composition of ter is commonly commingled by mixing certain matter placed upon the hides while in a stretched quantities of borax and starch together with Waor extended condition, and it has for its object to ter and thereafter by mixing with the same plascheapen the expense of mechanical appliance ter of Paris and applying the composition to the 0 commonly used and to render the process more hide while stretched upon an appropriate surface expeditious and simplified.

3. The process of setting a hide comprising stretching the hide on a surface, pasting the same to the surface, applying to the outer surface of the stretched hide a coating comprising plaster of Paris, borax, starch and water, removing the hide while covered with the coating, hanging it over a support, leaving it there until the coating sets, and removing the same.

4. The art of setting a hide which consists in stretching thesame, fastening the same to a surface, applying a coating of commingled plaster of Paris, borax, starch, and water in liquefied form to the outer surface of the hide,

lifting the hide from the surface and hanging it over a hanger with the exterior surface covered with the coating until the coating sets.

5. The process of treating hides in the manufacture of leather which comprises setting out a hide upon a setting table, applying a temporarily adhesive stiffening coating composition to the surface of the hide, removing the hide from the table, drying it and removing the coating therefrom.

6. The steps in the process of manufacturing leather which consist in maintaining a hide in setting out condition by means of a coating of a temporarily adhesive composition of matter and entirely removing said coating.

7. A temporarily adhesive composition of matter for use in drying hides, comprising plaster of Paris, starch, borax, and water, which becomes brittle upon drying and is completely and easily removable from the hide to which it has been applied, after the hide has dried.

8. A temporarily adhesive composition of matter for use in drying hides, comprising one part of plaster of Paris, one part of starch, one part of borax, and one part of water, which becomes brittle upon drying and is completely and easily removable from the hide to which it has been applied, after the hide has dried.

9. The process of treating leather which comprises removably attaching the leather to a smooth, rigid and rigidly supported surface, by means of liquid paste, setting out the leather upon said surface, coating the upper surface of the leather with a temporarily adhesive composition of matter whichis adapted to maintain it .in its stretched out condition, removing the socoated leather from the rigid surface, drying it, and removing the coating of the composition of matter from its surface, whereby the leather is obtained in a fiat condition and of substantially the same area as it had when removed from the rigid surface. r 10. A composition of matter comprising plaster of Paris, a carbohydrate, and a mineral compound having a' slight alkaline reaction, the composition being adapted to maintain a hide in its stretched out condition after it has been set out upon a setting board.
